REPLACEMENT OFFICE Shelley Ji Leazer, Charlotte, N. C. Application June 14, 1948, Serial No. 32,872

This invention relatesto improvements in the oil pan. of an automotive engine and more especially to a replacement screen for installing in an oil pan of an automotive engine. 7

Heretofore it has been necessary to discard manyof the oil pans removed from an automotive'engine due-to the fact that the screens, which are disposed in a partition in the oil pans, have been torn or punctured, thus admitting oil or lubricant containing sludge and'other foreign matter into an area in which only clean lubricant was supposed to be disposed. 'It' is therefore an object of this invention to provide a framework which is' made of a very light sheet 'metal and by removing the old worn screen from: the partition in the oil pan, this framework with a screen applied thereto may be inserted in the opening in which the screen was formerly mounted and is adapted to be bent around the edges of the openings to thereby securely mount the replacement screen in place in the openings, as well as preventing any openings which may be larger than the openings in the screen, at the edges of the screen.

Some of the objects of'the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawinga'in which Figure 1 is a side elevation of the lower portion of an internal combustion engine, with parts broken away;

Figure 2 is a vertical sectional view taken substantially along theline 2-2 in Figure 1;

Figure 3 is a top plan view taken substantially along the line 3-3 in Figure 1 and omitting the drip pan;

Figure 4 is a vertical sectional view taken substantially along the line 4-4 in Figure 3 and showing the drip pan associated with the oil pan;

Figure 5 is avertical sectional view taken substantially along the line 5-5 in Figure 3;

Figure 6 is an isometric view with parts in section showing the structure ofthe screened frame. -Refer1ing more specifically to the drawings, the numeral lll indicates an internal combustion engine having a crank shaft rotatably mounted therein on which the lower ends of connecting rods 2 are oscillatably mounted. The connecting rods 7 2 are provided with scoops at the lower ends thereof, and the engine III also has a conventional oil pan l6 secured to the lower surface thereof, by any suitable means such as screws I1, and this oil pan I6 is provided with a drain plug l8, and disposed between the oil pan I6 and the bottom surface of the engine In is a 5 Claims. (01. 184-406) 2 7 2| having a plurality "of therein, through which the conventional drip pan formed grooves 22 downwardly projecting scoops M of the connect ing rods |2 are adapted to move as the crank shaft rotates for feeding lubricant from the grooves 22 to the bearings of the conventional connecting rods |2.

The oil pan l6 has side walls 25 and 26, end walls 21 and 28, and a bottom 30. Extending upwardly from the bottom 30 and extending laterally from the walls 26 are spaced partitions 3| and 32. The partition 32 is disposed at a slight angle and has an opening 34 in the bottom edge thereof. The partitions 3| and 32 are:joined at their other ends by a longitudinally extending partition 35 which is spaced apart fromthe side wall 25 of the oil pan l6.

Extending from the partition 35 and being spaced slightly inwardly with respect to the partitions 3| and 32 are intermediate partitions 36 and 31 and these partitions 36 and 31 are connected at their other ends to a longitudinally extendingpartition 38 which is spaced from the side wall 26 of the oil pan 16. These partitions 36, 31 and 38 are provided with a plurality of rectangular openings 40 which normally have a screen covering the same and it is in these openings that this invention is adapted to be mounted.

The engine l0 is generally provided with a conventional oil pump, not shown, having a pipe extending from its intake side and the lower end of this pipe 45 is adapted to be connected to the upper end of a pipe 46 (Figure 2) which extends through the flanges of the drip pan 2| and the oil pan l6 and downwardly parallel to the side wall 25 of the oil pan Hi and then this pipe 46 is bent inwardly and passes through the wall 25 of the oil pan i6 and through the partition 35 adjacent the wall 25 to where it is bent downwardly and terminates adjacent the top surface of the bottom 30 of the oil pan Hi. This pipe 46 is welded as at 41 and 50 as it passes through the flange and the sidewall 25 of the oil pan IS.

The drip pan is provided with an overflow partition .55 and there is an opening 56 cut in the drip pan adjacent the partition 26 to thereby permit any excess lubricant disposed above the dripspan 2| to pass over the partition 55, downwardly through the opening 56 and this lubricant will pass into that area defined by the wall 26 of the oil pan I6 and the partition 38, and will pass through the opening 34.

Presuming that a lubricant had originally been stored within the oil pan l6, any lubricant that is drawn into the engine through the pipe 46 must,

of course, enter that area defined by the partitions 35, 36 and 31, as well as the partition 38 and must therefore pass through the openings 40 in the partitions to thus insure that any foreign matter will be filtered out of the lubricant as it moves in to the area defined by the partitions 3-5, 36, 31 and 38.

It is thus seen that in the event that the screens that cover the openings 40 are torn or the openings in the screens are u duly large, a considerable amount of sludge and the like would be permitted to enter through the openings 40 into the area in which the lower end of the pipe 46 is disposed and thus the pan lfilwould have to be discarded.

In order that these oil pans 16 may be reused, I have provided a, framework which may have as many openings therein as desired, to cooperate with the openings 18 in the partitions 35, 36, 31 and 38, and this framework is broadly designated by the numeral 66. This framework 60 comprise a flat portion62 which has extending upwardly therefrom in Figure 5, a vertically dis posed portion 63 and this portion 63 has mounted thereagainst a screen wire 65, the outer edges of which are spaced a, substantial distance from the outer edges of the upwardlyextending portion 63 and then this upwardly extending portion 53 is bent over upon itself as at 68 in Figure 5, and inasmuch as the material of which this framework 68 is preferably made is of a very light metal, this portion 66 is thenihammered or fastened tightly against the outer edges of the screen '54 to thus confine the screen 3 on the frame- Work 50. 7

The-framework 6G is then inserted in the openings 40 in the manner shown in Figure 6 and the innermost edges of the horizontal portion 62 of the framework fifl are bent inwardly as at 58 around the adjacent portions of the partitions 36,51 or 38, as the case may be,.to thus secure the framework 69 in the openings 40 of the partitions.

' By referring to Figure 3 it may be observed that the framework 68 may be bent at right angles as at 10 so that the framework 50 may be applied over the openings 48 in both of the partitions 3 5 and 3B and may be made of one piece, if desired.

It is thus seen that} have provided means for covering the openings 40 in the partitions 36, 3'! and 38 with screen in such a manner that a discarded oil pan {6 may be reused.

In the drawings and specification there has.

been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic andrdescript-ive sense only, and not for purposes of limita. tion, the scope of the invention being defined in the claims.

I claim: 1
